Carbon-remover



UNITED. STATES PATENT FFHCE.

CARBON-REMOVER.

No Drawing.

To all whom it may concern:

Be it lmown that I, ZIMMOND J. OLAF, a citizen of the United States, anda resident of Malvern, Chester county, Pennsylvania, have inventedcertain Improvements in Carbon-Removers, of which thelfollowing is aspecification.

My invention relates to compounds or compositions of matter employed toremove carbon from the cylinders of internal combustion engines. Whilemy improved carbon remover is particularly adapted for use for looseningcarbon from the cylinders, pistons, valves, spark plugs and other partsof an internal combustion engine, it may be employed under anyconditions where deposits of carbon interfere with the proper operationof any mechanical device or moving part clogged by such deposit.

The important object of my invention is to -provide a simple andeflicient mixture, compound, or composition of matter, that will serveto loosen the carbon and render it friable, and permit it to be blownout with the exhaust after it has been permitted to remain in contactwith the carbon deposit for a period of a few hours.

The material forming the subject of my invention maybe introduced intothe cylinders at any time after the motor has been stopped, and inpractice I usually place a small portion of the compound or compositionof matter in the cylinders at night, and after remaining in the sameover night,

for instance, the loose carbon separated by the action of my improvedcompound may fie blown out with the exhaust when the engine is startednext day.

Specification of Letters Patent.

Patented Feb. 15,1921.

Application filed August 17, 1917. Serial No. 186,702.

1 mg proportions:

Carbolic acid 2 parts, Alcohol 3 parts, Ammonia water 26 2 parts.

The several ingredients may be of the usual commercial character,purchasable in the open market, and for the alcohol I may use woodalcohol. Aqua ammonia of 26 is preferably employed as giving satisfactory results, although ammonia water of dif ferent strengths may besuccessfully emp Iii use, I place bout one ounce of my improved carbonremover in each cylinder, and the same may be introduced through thespark plug opening; the latter being removed for the purpose and thenreplaced. If desired, the spark plug may be dipped in the mixture sothat any carbon attached thereto may be loosened and subsequentlyremoved.

I claim:

A compound or composition of matter for removing carbon from gas enginecylinders and the like, comprising a mixture of carbolic acid,substantially two parts; a low boiling alcohol, substantially threeparts; and ammonia, substantially two parts.
